Édouard Challe is a Columbia-École Polytechnique Alliance Visiting Professor. He is an Associate Professor of Economics at École Polytechnique and will visit Columbia University's Department of Economics in the 2015-2016 academic year.

Bruno Martinaud is Professor of Technology and co-Director of the Technology Venture Master Program at Ecole Polytechnique. He has taught courses in the creation of Technology Start-ups with the aim of introducing students to the process of creating and developing technology start-ups, as well as their technical, marketing, and financial environments, in the context of innovation and research.

Jacques Biot is the president of Ecole Polytechnique. An École Polytechnique graduate (Class of 71) and engineer from the “Corps des Mines”, Jacques Biot dedicated the initial years of his professional career to industrial recovery and innovation funding within the Ministry of Industry and Research. He then served as the Key Policy Advisor, in charge of “Industry and Technology” in the Prime Minister's office until 1985.

Professor Jean-Francois Laslier is a professor of Economics at the Paris School of Economics and at Ecole Polytechnique, where he teaches Public Economics, Political Economy and the Theory of Democratic Choice. He deals with the definition of collective evaluation criteria (welfare, equality, efficiency) and examines collective institutions such as direct democracy, government, delegation, and public monopolies. His research interests include Social Choice Theory, Game Theory, and Experimental Economics, in particular voting rules, voter behavior, and party strategies.

M. Edouard Challe is a CNRS researcher and associate professor of Economics at Ecole Polytechnique. Previously, he was the deputy head of department and director of Pole de Recherche en Economie et Gestion-CECO, a research fellow at CREST, and a consultant with Banque de France. M. Challe received his PhD in Economics as well as his M.A. in Philosophy and M.A. in Economics at Université Paris Ouest.

As a PhD student in Economics, my research focuses on habit persistence in consumption. The Alliance Mobility Grant will allow me to meet with specialists of this domain, who developed and explored the implications of the very type of habit formation I am interested in -when habits form over individual types of goods. It will also give me the opportunity to take part in the rich academic life of the Economics department at Columbia University.

Philippe Jacquet is the Research Director in Institut National de Recherche en Informatique et Automatique (INRIA). His areas of research are largely concerned with telecommunication and information theory, wireless networks, mobile ad hoc networking, algorithms. He holds 8 patents, and is also a part-time professor of computer science at École Polytechnique in Paris.

In the last decade the online social media services have seen a huge expansion, and as a result, the value of information within these networks, increases dramatically. Interactions and communication between users help predict the evolution of information in online social networks, and the ability to study these networks can provide relevant information in real time. I believe that my research visit at Columbia University, with the support of the Alliance Doctoral Mobility Grant, will address the above challenges, and it will span my horizons in research in general.

Philippe Drobinski is a Senior scientist at Laboratoire de Météorologie Dynamique/Institut Pierre Simon Laplace and an associate professor at Ecole Polytechnique, teaching courses on meteorology and the environment.

Frederic Brechenmacher is a professor of history of science and technology at Ecole Polytechnique. His research areas include the history of the Mathematical Sciences – 19th and 20th centuries; history of linear algebra; circulation of knowledge and algebraic practices; and th mathematical works of Camille Jordan (1865-1922).

Professor Raphanel will be working at the lab of Jeffrey Kysar (Professor of Mechanical Engineering, Columbia University) at Columbia's School of Engineering and Applied Science, for the 2013-2014 academic year.

X-Forum is the l'École Polytechnique's annual forum, which brings together nearly 2000 students - including 1000 Polytechniciens - with 150 companies, Écoles, and international universities.

Every year, the École Polytechnique trains 500 engineers whose skills are recongnized throughout France and the world. Their high-level pluridisciplinary training enables them to hold leadership roles in all areas of industry, service, research, and administration.

Denis-Didier Rousseau is a Senior Research Scientist at the French Centre National de la Recherche Scientifique (CNRS), the Director of CERES-ERTI, and an Adjunct Research Scientist at the Lamont-Doherty Earth Observatory of Columbia University.

The project proposes a Columbia-École Polytechnique collaboration for research at the intersection of theoretical physics and materials science with the goal of our understanding of the remarkable electronic properties of transition metal oxide materials such as the ‘high transition temperature’ copper-oxide superconductors by developing an ab-initio theory of electronic phases and dynamics in the strongly correlated situation.

Antoine Georges is a Professor at the Collège de France and the École Polytechnique. His research interests are in theoretical condensed matter and statistical physics. Most of his recent research deals with the physics of strong electron-electron interactions. These interactions have spectacular effects in materials such as transition metals and their oxides, high-temperature superconductors, f-electron compounds and organic conductors.

(Fall 2013) Research Internship between the Ecole Polytechnique and Columbia University in Mathematics, Applied Mathematics, Mechanics, Physics, Chemistry, Biology, Economics, or Computer Science. Open to advanced undergraduate students, Master and PhD students from Columbia wishing to spend 3 to 6 months at one of the Ecole Polytechnique laboratories.

(Spring 2013) In the coming weeks, we will be producing a short video about the Alliance Program. The Alliance team and the producer of the video would like to gather testimonials from current and former students of Alliance Joint Programs and Dual Degrees.

Suppose that a group of individuals are about to interact strategically with one another. Each of them holds private information that is relevant for the interaction that is about to take place. If these individuals are allowed to communicate with each other, when is it the case that each of them fully reveals her private information to all the others? We provide answers to this question under the assumption that individuals communicate by exchanging evidence.

“My research visit at Columbia University deals with the experimental investigation of the theoretical models developed during the past years' research at Ecole Polytechnique. This project not only broadens the spectrum of my Ph.D. dissertation but also initiates an active collaboration between Laboratory of Physics of Thin Films and Interfaces (Ecole Polytechnique) and Columbia Laboratory for Unconventional Electronics (Columbia University).”

Reflecting on his stay at Columbia under the Alliance Doctoral Mobility Program 2012-2013, Chang Hyun Kim told us that:“My research visit at Columbia University deals with the experimental investigation of the theoretical models developed during the past years' research at École Polytechnique.
